The dollar rose against the yen on Tuesday as Japanese investors and companies rushed to cover a shortage of the U.S. currency before their fiscal year end, but sentiment remained fragile as the global coronavirus crisis showed no signs of abating. China's yuan held steady in offshore trade but could be buffeted by the release of a key manufacturing survey later in the day as investors count the economic cost of the coronavirus, which first emerged in China late last year. The pound fell against the greenback and the euro as a sovereign ratings downgrade continued to weigh on sterling, underlining the strain on public finances from a much needed massive fiscal stimulus. Tuesday is the last trading data for Japan's fiscal year and the end of the quarter for major investors elsewhere, which could lead to some volatile swings as big players in the currency market close their books. China's currency eased on Monday after the People's Bank of China unexpectedly cut its reverse repo rate by the most in almost five years.
